Application filed January 24,1898- Serial No. 667,738. (No model.)

fl'o' tZZ wit" Be itlr a citizen 0 United States, residing at Watel-bury, he county of New Haven and State o ieeticut, have invented certain new ll improvements in Devices for Stop es or Punctures in Pneumatic v Tire er Substances; and I do declare the to to be afull, clear, and exact description of the invention, such as will enable others elizilledin the art to which it appc'rtains to ma ice and use the same.

This invention relates to that class of devices used to mend or fill holes or punctures in pneumatic tires; and the object of my invention is to provide means by which a hole or puncture in a pneumatic tire may be quickly and substantially filled, so as to be air-tight. l attain this object by means of the device or machine illustrated in the aecompanyiihg drawings, in which Figure l is a plan of the device or machine. Fig. 2 is a side elevation of the lever C; Fig.

, 3, an end view of said lever; Fig. 4, a detail view of the tube, its ends, and lever-support; Fig. 5, an end viewof the same; Fig. 6, an end view of the collar with set-screw; Fig. 7, a side View of the same; Fig. 8, a perspective view of the rod A used singly.

Similar letters refer to similar parts throu ghout the several views.

The rod A, provided with the loop 0 on one end thereof and the slot 1) cut into its other and tapered end, is operated with the other parts of the device or machine through the tube 13, and when thus operated the said rod carries the collar E, secured thereto by the screw ll tliroughtlic tube-slot Ct.

The tube 13 constitutes the frame on or through which each of the other parts of the device or machine operates. The tube B has both of its ends closed or covered, excepting the holes (2- and e, to admit the rod A, and has the longitudinal slot c and the transverse slot f to admit the screw 11 and provide a traveling space and lock for the screw II. The tube 13 is provided at its end through which the tapered end of the rod extends with the cover I, having the projecting lip g,which serves as a guide to hold the strands of rubher in place and is also used to compress the strands together in the operation of unlocking the device, as hereinafter described.

The collar E may-be secured to any desired part of the rod A by loosening the screw ll, then pushing the rod A through the collar E to the desired position, and tightening the screw ll.

The lever-support F is secured to the tube .13 near the edge of the slot u and is provided with a scrcwholc to receive the screw G, which secures the lever C thereto.

The angle-lever C is provided with the slots 7t it at its end nearest the screw-hole, which secures said lever to its support F.

This combined device or machine may be operated as follows: by pushing the rod carrying the collar E and the screw ll down until the screw ll comes to the end of the slot, turning the rod until the screw slips into the locking-slot f, pushing the long end of the angle-lever 0 against the screw ll, inserting the end of a piece of rubber string in one of the slots h in the short end of the angledever C, then stretching the rubber string slightly and passing it between the long end of the angle-lever U and the projecting lip g and through the slot b' on the end of the rod A, then back between the said long end of the lever and said lip to the short end. of the lever, thou turning the short end of said lover and repeating until several strands of rubber extend from the short end of said lever be-- twecn'the long end of said lever and said lip and over the end of and through the slot in said rod, the second end of the strand of rubber being passed through the other slot h to secure it, placing a drop of cement upon the strands of rubber near the end of the rod, pushing the end of the rod together with the strands of rubber through the hole or puncturc to be filled until the end of the tube A quite or nearly touches the outer surface of the substance containing the hole or puncture, turning the .rod 13 until the screw ll comes in line with the slot A,and While holding the tube in its above-described position .vvithdrawing the rod through the hole or puncture. W hen the rod is turned to the right to bring the screw H in line with the slot u,,the long I00 end of the lever is thereby automatically pushed toward the lip 'g and the strands of rubber at that point are compressed and firmly held untilthe end of the lever is released by passage of the screw H in the slot a toward the fulcrum of the lever. When the screw H passes the point in the'slot at opposite the screw G, the short end of the lever is drawn around by the tension of the strands of rubber until the lever assumes the position shown in Fig. 1 by the dotted lines, when the strands of rubber slip over the short end thereof and are released from the device.

The advantages of this over other devices are that it can be very quickly operated, the puncture or hole issecure'ly stopped, and the most inexperienced person can do as thorough work with it as though skilled in its use.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent; is.-

1. The combination of the rod A provided with a slot in one end thereof; the tube B provided with the longitudinal slot a, the tra usverse slot f and the lever-support F; and

the lip g; and the lever 0 provided with the slots h Witnesses:
